Abstract
Description
1. Title of the invention
[0001] Garment with a shape-retaining shirt collar for use under outerwear. 2. State of the art
[0002] Traditional dress shirts have long been a staple of formal and semi-formal attire. They typically feature a collar reinforced with interlining, giving the wearer a neat and tidy appearance. However, when worn under sweaters, pullovers, or cardigans, dress shirts are often uncomfortable because they appear bulky, add multiple layers of fabric, and restrict movement.
[0003] Undershirts, on the other hand, are lightweight, stretchy, and comfortable to wear, but they lack a collar and therefore don't offer a formal look. The market currently offers no solution that combines the visual advantages of a dress shirt with the comfort of an undershirt. 3. Problem underlying the invention
[0004] There is a need to provide a garment that conveys the formal look of a shirt but offers the comfort of an undershirt. In particular, the collar should remain stable even when the garment is worn under close-fitting outerwear. 4. Solution to the problem (invention)
[0005] The invention relates to a garment, in particular an undershirt, with the following features: 1. Hull section: ◯ Made from an elastic knit fabric material, consisting mainly of cotton with an elastane component. ◯ Slim-fit cut that fits snugly to the body and does not add bulk. 2. Collar: Made from woven material. ◯ Two-layer construction with reinforced insert (interlining), preferably thermally fixed. ◯ Insert with medium to high stiffness, so that the collar remains upright even during movement. 3. Button placket (plaque): ◯ optionally with a short button placket to visually imitate a classic shirt 5. Advantages of the invention • Comfort: Thanks to the elastic, breathable material, the garment feels like an undershirt and fits comfortably against the body. • Elegance: The specially constructed, reinforced collar ensures that the garment gives the impression of a classic shirt, even under sweaters or cardigans. • Versatility: Suitable for office, leisure and travel, as no ironing is required and the product is easy to care for. • Level of innovation: So far, no comparable garment exists that combines the look of a shirt with the comfort of an undershirt.
